Key Features
-
Universal Sensor Fit: Accepts any Endress+Hauser sensor with Pg 13.5 thread (pH, ORP, conductivity, DO), making it a versatile platform across multiple measurement types.
-
Chemical Resistance: PVDF construction withstands aggressive media including chlorine, acids, and oxidizing agents — far superior to standard PVC or PP in many process waters.
-
Flexible Installation: Can be immersed directly into tanks via a mounting flange or installed in a by-pass flow cell for representative sampling from a pressurized line.
-
Secure Compression Seal: Integrated Pg 13.5 compression nut and seal ring ensure leak-tight sensor retention under rated pressure/temperature.
Applications
-
Wastewater Neutralization Basins: Immersion mounting of pH electrodes (CPS11D) for continuous pH monitoring.
-
Chemical Dosing Skids: In-line flow-through installation for conductivity (CLS21) or ORP (CPS12D) verification.
-
Cooling Tower / Boiler Blowdown: Sampling loop mounting for water quality sensors.
-
Potable Water Disinfection: Mounting of free chlorine (CCS50D) or ozone sensors in sample streams.
